MOLD FOR MAKING CLAY PIPES, 800.

SPECIFICATION forming part of Letters Patent No. 354,216, dated December14, 1886.

Application filed May 1, 1886. Serial No. 200,764. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES A. PERRY, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Molds forMaking Olay Pipes and other Articles, of which the following is aspecification. 4

This invention relates to an improved mold for making clay pipes,wall-copings, and other articles of oval and other cross-section; andthe invention consists of a mold for making clay pipes and otherarticles which is provided with a basesection and a fixed interior core,a former, an independently-movable lockinglever pivoted to thesupporting-rod of the former, a fixed vertical rod attached to thebase-section, and a bracket-arm attached to the former and guided on thevertical rod during the up and clown movements of the former.

In the accompanying drawings, Figure 1 represents a vertical centralsection of my improved mold for making clay pipes and other articles,shown in a closed position. Fig. 2 represents a vertical central sectionshowing the former lowered. Fig. 3 is a side view of the mold, and Fig.4 a bottom view of the same.

Similar letters of reference indicate corresponding parts.

The mold consists of the usual cylinder, A, into which the clay ischarged and forced down by a plunger. (Not shown in the drawings.) Atthe lower part of the cylinder A is arranged the basesectiou B, andcentrally to the same the core 0, which is supported on a fixed centerrod, 0. The former D is supported on the former-rod D, which isvertieally reciprocated, so as to open or close the bottom of the moldin the usual manner. The former D serves, in connection with thebasesection and core, to form the shoulder at one end of the clay pipeor other article. It is rigidly attached to the upper end oftheformerrod D and accurately fitted to the base-section B and core 0.

The parts thus far described have been used heretofore in pipe-molds,and I therefore do not claim the same.

My improvements consist in pivoting the fixed hooks, E, attached to thebase-section B, which hooks extend in opposite direction, so as toretain the lever E, as shown in Figs. 1, 3, and 4. To prevent the formerD from turning on its axis when it is unlocked by the motion of thelever from the base-section B, the former is guided in its up-and-d ownmo tion by a fixed bracket-arm, f, on a fixed vertical rod, f, that isrigidly attached to the base-section B, as shown in Figs. 1 and 3. Thearrangement of the independently-movable lever E permits the locking andreleasing of the former D without producing the axial turning of thelatter, so that pipes of oval or other cross-sections can be made inmolds of corresponding cross-sections, in which case the former cannotbe turned with the lever in opening or closing the mold, as in the moldsheretofore in use.

The independent movement of the lockinglever and the vertical guiding ofthe former form the novel features of myimproved mold, by which the sameis adapted to mold pipes of any cross-section.

Molds of this construction are also adapted for making wallcopings andother articles, in which case two copings are made at the same time inthe form of a pipe of corresponding cross-section, said 'copings beingconnected at their abutting ends, formed with shoulders at one end inthe same manner as other pipesections, and separated after burning attheir abutting edges in the well-known manner.

Having thus described my invention, I claim 9 5 as new and desire tosecure by Letters Patent- 1. The combination, in a mold for clay pipes,of a base-section and a core corresponding to the cross-section of thepipe, a former fitted to the base section and core, an indelooking-leverpivoted below the base-section to the former-rod, and adapted to lock orrelease the former without turning the same, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in pres ence of two subscribing witnesses.
